我创建了一个过滤器，在我的博客文章的图像上添加了一个pin按钮，这在玩了很多次之后就奏效了。几周后，我更新到3.6.1，过滤器停止工作。

新版本中是否有更改，阻止了对\\u内容的筛选工作？

function cd_insert_pinterest($content) {
        global $post;
        $postID = $post->ID;
           if( is_singular() && is_main_query() ) {
                $posturl = urlencode(get_permalink()); //Get the post URL
                $pindiv = \'<span class="pinterest-button">\';
                $pinurl = \'<a href="http://pinterest.com/pin/create/button/?url=\'.$posturl.\'&media=\';
                $pindescription = \'&description=\'.urlencode(get_the_title());
                $pinfinish = \'" class="pinning"></a>\';
                $pinend = \'</span>\';
                $pattern = \'/<img(.*?)src="(.*?).(bmp|gif|jpeg|jpg|png)" (.*?) width="(.*?)" height="(.*?)" \\/>/i\';
                $replacement = $pindiv.$pinurl.\'$2.$3\'.$pindescription.$pinfinish.\'<img$1src="$2.$3" $4 width="$5" height="$6" />\'.$pinend;
                $content = preg_replace( $pattern, $replacement, $content );
                $newpattern = \'/<a(.*?)><span class="pinterest-button"><a(.*?)><\\/a><img(.*?)\\/><\\/span><\\/a>/i\';
                $replacement = \'<span class="pinterest-button"><a$2></a><a$1><img$3\\/></a></span>\';
                $content = preg_replace( $newpattern, $replacement, $content );
           }
                                return $content;

}

add_filter( \'the_content\', \'cd_insert_pinterest\');
